Abstract

We studied magnetic vortex oscillations associated with vortex gyrotropic motion driven by spin-polarized out-of-plane dc current by analytical and micromagnetic numerical calculations. Reliable controls of the tunable eigenfrequency and orbital amplitude of persistent vortex oscillations were demonstrated. This work provides an advanced step toward the practical application of vortex oscillations to persistent vortex oscillators in a wide frequency $(f)$ range of 10--2000 MHz and with high values of $f/\ensuremath{\Delta}f$.
